Last time I built a computer I had never heard of ATA, ultra ATA, Serial ATA, SATA or any of this, I don't know what its all about really, but I just need some good drives mirroring each other in a computer I already have, this is all compatible, correct? Western Digital Caviar SE WD1600JS 160GB 7200 RPM SATA 3.0Gb/s Hard Drive - OEM x2 GENERIC 18" 2-Head Red SATA (SERIAL ATA 150) Cable Model SERIAL ATA 18 - OEM Koutech PSA150 PCI SATA Dual Channel Host Controller Card - Retail Also, I will be putting these into a computer with IDE drives currently, will I be able to boot from these new drives or will I still have to boot from an IDE drive connected to the motherboard? Thanks. EDIT: also looking at the pics I see the power connection for these drives is different? Does it come with something that connects to the standard power cable from my PS?
